DESCRIPTION The TSH95 is a quad low power high frequency op-amp, designated for high quality video processing. The device offers an excellent speed consumption ratio with 4.5mA per amplifier for 150MHz bandwidth. High slew rate and low noise make it also suitable for high quality audio applications. The TSH95 offers 2 separate complementary STANDBY pins : u STAN DBY 1 acting on both n 1 & 2 operat ors u STAN DBY 2 acting on both n 3 & 4 operat ors They reduce the consumption of the corresponding operatorS and put the output in a high impedance state.

V CC standby
STANDBY MODE To put the device in standby, just apply a logic level on the standby MOS input. As ground is a virtual level for the device, threshold voltage has been refered to VCC+ at VCC+ - 1.6V typ. In standby mode, the output goes in high impedance in 200ns. Be aware that all maximum rating must still be followed in this mode. It leads to swing limitation while using the device in signal multiplexing configuration with followers, differential input voltage must not exceed 5V limiting input swing to 2.5Vpp. SAMPLE AND HOLD

PRINTED CIRCUIT LAYOUT As for any high frequency device, a few rules must be observed when designing the PCB to get the best performances from this high speed op amp. From the most to the least important points : LARGE SIGNAL FOLLOWER RESPONSE
u Each power supply lead has to be
by-passed to ground with a 10nF ceramic capacitor very close to the device and 10F capacitor.
u To provide low inductance and low resistance common return, use a ground plane or common point return for power and signal.
u All leads must be wide and as short as possible especially for op amp inputs. This is in order to decrease parasitic capacitance and inductance. STATIC OPEN LOOP VOLTAGE GAIN
u Use small resistor values to decrease time
constant with parasitic capacitance.
u Choose component sizes as small as possible (SMD).
u On output, decrease capacitor load so as
to avoid circuit stability being degraded which may cause oscillation. You can also add a serial resistor in order to minimise its influence. INPUT OFFSET VOLTAGE DRIFT VERSUS TEMPERATU RE
